酸浸—萃取工艺在石煤提钒工业中的设计与应用

介绍酸浸－萃取工艺在一个日处理５００ｔ钒矿石水冶厂的设计与应用情况。该矿五氧化二钒的原矿品位为１．１％，设计采用原矿直接硫酸浸出，浸出矿浆经固液分离，浸出液送萃取－反萃，反萃液经氧化沉淀得五氧化二钒产品，其浸出率为７５％，总回收达到６５％，比钠化焙烧工艺高出１５％以下，产品质量达到国家标准。

Design and Application of Acid Leaching-Extraction Processing in Bone Coal Extracting Vanadium Industry

This article introduced the design and application of acid leaching-extration processing in the bone hydrometallugy plant at a rate of 500 tons per day. Through sulfuric acid's leach directly, solid-liquid seperration, extraction and reversal-extraction, oxidization and precipitation, the product V2O5 is achieved whose raw ore grade is 1.1%. The leaching rate is up to 75%and total recovery rate up to 65%, which is about 15%higher than roasting-sodium processing and the products quality fit for Chinese standard.
